NRM refers to the integrated management of land, water and biodiversity assets.
There are 54 regional NRM bodies across Australia, including three in Tasmania.
Tasmania minister for primary industries and water Jo Palmer said the NRM North, South and Cradle Coast groups played a key role in delivering both state and national environmental and agricultural priorities.
"Established in 2003, the state's three NRM organisations provide advice to the Tasmanian government, on matters relating to land, water and our biodiversity assets," she said.
"All three NRM organisations deliver strategic priorities for their regions to support healthy soils, farmland, rivers and other natural resources, which underpin our world-class agricultural sector and our environment."
Palmer said the state government boosted funding to the groups to guarantee each group received about $467,000 each year, for the next three years.
"State government funding supports administration, development and implementation of strategic projects, and community engagement, and provides for each regional NRM organisation to leverage significant additional investment into our state," she said.
"I would like to extend my appreciation to all the NRM staff and volunteers and acknowledge the great work they have done over the past 20 years and will continue to do for many years to come."
